Problems solved by technology

In practical application, designers need to manually draw the road outline through architectural design software, which will reduce the design efficiency of designers; in addition, in the existing architectural design software, models that automatically generate road outlines have also been developed. However, the operation is cumbersome and has certain specification requirements. If the user's operation does not meet the specification requirements, the road outline cannot be automatically formed.
It can be seen that the existing methods for generating road contour lines are relatively cumbersome and have certain limitations.

Embodiment 1

[0049] Embodiments of the present invention provide a method for generating road contours, such as figure 1 As shown, the method specifically includes the following steps:

[0050] Step S101: Receive a generation instruction, and parse out the original road centerline and road width information contained in the generation instruction; wherein, the original road centerline is composed of at least two ordered and end-to-end vector edges.

[0051]In this embodiment, the road centerline is the positioning and orientation line of the road and related projects, and the road outline is generated on the basis of the road centerline.

[0052] Specifically, the original road centerline is represented by a two-dimensional edge list; wherein, the two-dimensional edge list includes a plurality of nodes, and each node corresponds to a vector edge in the original road centerline; in addition, Each node includes: a data field and a pointer field; wherein the data field is used to store the p...

Embodiment 2

[0107] An embodiment of the present invention provides a device for generating road contours, such as image 3 As shown, the device specifically includes the following components:

[0108] The parsing module 301 is configured to receive a generation instruction, and parse out the original road centerline and road width information included in the generation instruction; wherein, the original road centerline is composed of at least two vector edges connected end to end;

[0109] A processing module 302, configured to process the two connected vector sides in the original road centerline as G1 continuous, so as to obtain the standard road centerline;

[0110] An offset module 303, configured to use an offset algorithm to offset two road edge lines on both sides of the standard road center line according to the road width information;

[0111] A generating module 304, configured to form a closed road contour line based on the two road edge lines.

[0112] Specifically, the proc...

Embodiment 3

[0138] This embodiment also provides a computer device, such as a smart phone, a tablet computer, a notebook computer, a desktop computer, a rack server, a blade server, a tower server, or a cabinet server (including an independent server, or A server cluster composed of multiple servers), etc. like Figure 4 As shown, the computer device 40 in this embodiment at least includes but is not limited to: a memory 401 and a processor 402 that can be communicated with each other through a system bus. It should be pointed out that, Figure 4 Only computer device 40 is shown having components 401-402, but it is to be understood that implementing all of the illustrated components is not a requirement and that more or fewer components may instead be implemented.

[0139] In this embodiment, the memory 401 (that is, a readable storage medium) includes a flash memory, a hard disk, a multimedia card, a card-type memory (for example, SD or DX memory, etc.), random access memory (RAM), sta...

Abstract

The invention discloses a method and a device for generating a road contour line, equipment and a readable storage medium. The method comprises the steps: receiving a generation instruction, and analyzing an original road center line and road width information contained in the generation instruction, wherein the original road center line is composed of at least two ordered vector edges which are connected end to end; processing two connected vector edges in the original road center line to be G1 continuous so as to obtain a standard road center line; according to the road width information, offsetting two road edge lines on the two sides of the standard road center line through an offset algorithm; forming a closed road contour line based on the two road edge lines; according to the method, the road contour line can be efficiently and stably generated according to the road center line in any form.

Description

technical field [0001] The present invention relates to the technical field of computer graphics processing, in particular to a method, device, equipment and readable storage medium for generating road outlines. Background technique [0002] In the field of construction, road contours are used to characterize the road width required for motor vehicle, non-motor vehicle and pedestrian traffic; businesses involved within the scope of road contours include: pavement, curbs, roadbeds, soft foundations, retaining walls, Inspect wells, foundation pits, pipes, trenches, etc. In practical application, designers need to manually draw the road outline through architectural design software, which will reduce the design efficiency of designers; in addition, in the existing architectural design software, models that automatically generate road outlines have also been developed. However, the operation is cumbersome and has certain specification requirements. If the user's operation does ...
